Cytotoxicity of cetyltrimethylammonium bromide (CTAB)-templated silica-coated gold nanorod (CGNR@SiO2) was confirmed to be severe even after the washing process because of the residual CTAB surfactant. Calcination to eliminate the CTAB template induced dissolution of the gold nanorod (GNR) core and caused a blue-shift in the longitudinal surface plasmon resonance (LSPR) mode of the GNR from the near-infrared

Zinc is currently extracted from sphalerite (ZnS) by either sintering-smelting or roasting-leaching. These high-temperature processes produce environmentally hazardous sulfur dioxide gas. Hence, sustainable zinc extraction calls for direct leaching at low temperatures. Here, we show that ferric methanesulfonate is a high performing lixiviant for this purpose. Using 0.8 M ferric methanesulfonate, 99

We demonstrate a facile one-step fabrication of flexible ridge waveguides by using the nanochannel-guided lithography (NCL) that enables continuous extrusion of a polymer that forms waveguiding core ridge on an undercladding polymer substrate. NCL utilizes a well-cleaved mold edge with microtrench patterns to slide continuously over a UV-curable liquid resin-coated substrate under conformal contact

Foam is used in many fields with excellent performance. Moreover, disinfectants with ethanol as the main ingredient have increasingly been used in people's lives. However, the foam research of an ethanol-water mixed system is still in the initial stage. In this work, a perfluoroalkyl polyoxyethylene ether phosphate salt surfactant (FEP-Na) was synthesized through a new molecular design. The surfactant

Steam-gasification of linear low-density polyethylene (LLDPE) waste to hydrogen-rich gas has been studied systematically over nickel (10 wt.%) loaded on a variety of supports (Al2O3, CeO2, and CeO2-ZrO2) synthesized using a novel solvent deficient method (SDM). The hydrogen selectivity order of the catalysts was reported as Ni/CeO2-ZrO2>Ni/CeO2>Ni/Al2O3. The highest catalytic H2 selectivity of the

This work introduces an efficient probe for sensitive and selective detection of Al3+ based on gold nanorods (AuNRs) with tannic acid (TA) surface modification. TA, which contains five digalloyl ester groups covalently attached to a glucose core, exhibits preferential complexation and binding to Al3+, leading to the formation of side-by-side assembly of AuNRs and consequently inducing a change in the

Compared with the traditional water-based fracturing fluid thickener guanidine gum, the price of synthetic polymer is relatively low, and the temperature resistance, shear resistance and viscoelasticity of the formed fracturing fluid are better. Therefore, the fracturing fluid formed by the crosslinking of HPAM and organic metal crosslinker will become one of the hot spots in the research of water-based
